Remote Access VPN - issue

SOL10 — Mon, 11 Mar 2019 13:52:07 GMT

HI all

im trying to set up a Remote Access VPN on pix 6.3 (where once connected you are assigned only 1 IP and that IP can only RDP to one server 192.168.1.17) and although i connect to the the vpn ok, i cant RDP to that server. on the vpn client, the sent bytes are going up but the recvd bytes are 0.

on the remote server I have added a static route as follows:

route add 192.168.10.0 mask 255.255.255.0 192.168.1.245(inside interface of pix) its on same segment

below are the VPN configs:

access-list split-tunnel permit ip 192.168.1.0 255.255.255.0

ip local pool RA_VPN_SUPPORT 192.168.10.11 mask 255.255.255.0

nat (inside) 0 access-list NONAT

crypto ipsec transform-set RA_VPN_SET esp-3des esp-sha-hmac

crypto dynamic-map DYN_MAP 4 set transform-set RA_VPN_SET

crypto map CRYPTO_VPN 99 ipsec-isakmp dynamic DYN_MAP

crypto map CRYPTO_VPN client configuration address initiate

crypto map CRYPTO_VPN client authentication RA_VPN_AAA

Do you have the access list "NONAT" specified in your config?

Do you have other working tunnels on the device?

Have you used the command "sysopt connection permit-ipsec" or allowed access to the LAN address on the outside access list of the PIX?

Does the server have an appropriate return route?

Can you ping the inside of the PIX from the VPN client if you specify "management-interface inside" ?

yes the server has a static route to 192.168.10.0 via inside interface of pix as on same segment
